What About Roi Et Airport (ROI)?
Roi Et Airport (ROI) has only 2–3 daily flights to Don Mueang (DMK) in Bangkok, operated by Nok Air and Thai Lion Air. From DMK, you would need to transfer to another flight to Khon Kaen (KKC) or take a taxi across Bangkok. This is not recommended as a way to reach KKC – the total cost (฿4,000–6,000) and time (6–8 hours) far exceeds a direct taxi.
When You Might Consider Flying (Indirectly)
- ❌ Almost never for this specific origin-destination pair.
- ✅ Only if you are combining Roi Et → Bangkok → Khon Kaen as part of a multi-city itinerary.
Bottom line: Taxi or minibus is faster, cheaper, and more environmentally friendly for the Roi Et–Khon Kaen corridor.

- Bus: Local buses have small luggage holds; if you have a big backpack, keep it with you (pay for a second seat if necessary).
